I’ve installed Toad 12.5 today over an existing 12.1 installation. After install I want to start Toad 12.5 and it hung on startup. The splash screen pops up and tell’s me “Checking for critical files…” And then nothing happens.
I run Toad on a Windows 7 Professional Client, CPU: Intel Dual Core 2.70 GHz, 4 GB RAM, 32-bit. Oracle Client is also 32-bit. Version 12.1 works fine.
Just checking here…can you verify that you downloaded the 32-bit version (since your using a 32-bit client), and not the 64-bit by mistake? I’m assuming
you used the ‘Toad for Oracle 12.5 Installer (for 32-Bit Oracle Client)’ link under ‘Base Edition’?

Are any of you using Norton AntiVirus? We’ve written on the forums about this known issue for quite some time - Norton has a huge lag between when new versions of apps debut and when they recognize them correctly. The workaround is to whitelist the toad.exe or better yet the toad install directory so that Norton will not interfere (wrongly) with toad running …
This seems to be the same problem that was discussed in the beta forum, but apparently the only solution was to run 64bit version of Toad with the 64bit Oracle client.
As a workaround "Run as Administrator" may work for you. In our testing there have been mixed results. If this does not work for you perhaps your system administrator could elevate your privileges to include write access to Toad's installation directory.
Toad is attempting to obtain an exclusive lock on a couple of files to be sure that no other application (specifically a second copy of Toad) is accessing them at the same time. Toad does not write to its installation folder, but the current code requires
write access for the locked file check.
Correct, if you have read/write access to the “Toad for Oracle 12.5” folder under program files this will not happen. Alternatively you can install Toad somewhere
other than program files
